CHURN-OPERATING MECHANISM.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed March 23, 1908. Serial No. 422,739.

T 0 all whom it may concern:

Be it known that I, \VILLIAM H. COLMAN, a. citizen of the United States,residing at Paducah, in the county of McCracken and State of Kentucky,have invented a new and useful Churn-Operating Mechanism, of which thefollowing is a specification.

This invention relates to a mechanism for operating churns and otherdevices requiring a vertically reciprocating motion; and has for itsobject to provide a simple, strong and economical structure forimparting such motion to a churn dasher rod: movement in one directionbeing produced by manual or pedal action and in the opposite directionby resilient means.

A further object of the invention relates to means applied to themovable portion of the mechanism for keeping insects away from the mouthof the churn, when the device is applied thereto, and further meansattached to the same part of the mechanism for operating one or morefans to cool the person operating the churn when the weather is warm.

With these and other objects in View the invention consists of certainnovel combination construction and arrangement of parts hereinafterdescribed and claimed, and illustrated in the accompanying drawing inwhich- Figure 1 represents a perspective view of the operating mechanismapplied to a reciprocating churn, and Fig. 2 a detail of construction.

The churn body 1 has a cover 2 through the center of which is a hole forthe passage of a rod 3 attached to a dasher not shown within the body.This old and well known type of churn is supported on a base board 4upheld from the floor by two parallel cross strips 5 at opposite ends ofthe base boards to give greater steadiness thereto. Fixed to the baseboards at are two vertically disposed guide bars or rods 6 between whichthe churn is placed and which project above the same to a suitableheight for the purpose required. Surrounding each guide bar or rod is acoiled spring 7 their lower ends resting on the base board and theirupper ends supporting a cross head 8 having a vertical opening througheach end for the guide rods 6 to pass through and a similar opening inthe center for the dasher rod 3 which latter rod is fixed in adjustedposition by a thumb screw 9 or other suitable means.

If the thumb screw 9 be loosened the dasher and cover 2 may be removedfrom the churn and cream or milk placed in the body 1. Returning thedasher and cover to place, the former is adjusted to the highestposition required and secured by the thumb screw 9 bearing against thedasher rod 3. Now, by pressing on the cross head 8 or dasher rod 3, thedasher is forced downward through the cream or milk to or near thebottom of the churn agitating the cream or milk and coinpressing thesprings 7. \Vhcn pressure is removed from the mechanism the compressedsprings restore the parts to their initial position. It will thus beseen that by a succession of such operations, manual power being appliedonly on the downward stroke of the dasher. butter will be rapidly andeasily made with slight expenditure of power on the part of the personoperating the mechanism.

Manual operation of the mechanism may be assisted or replaced by a pedalattachment such as that shown in the drawing which comprises a verticalstandard or guide frame 12 formed preferably of two upright parallelbars rigidly connected together at the top and supported on one cornerof the base board 4 by inserting their reduced lower ends into sockets13 made in the base and fastening the standard in position by a thumbscrew 14 or other convenient means. Pivotally attached to the bottom ofthe standard 12 between the parallel bars thereof is an arm 15projecting outwardly from the base board when in use, its free endresting on the floor. Fulcrumed to the outer end of the arm 15 by ahinge 1G is a pedal lever 17 its free end extending through the standardor guide frame 12 toward the churn where it is fastened to a cord, chainor other connection 18 reaching upwardly to the cross head 8. For thesake of illustration, the drawing shows a cord tied to the inner end ofthe pedal with a snap hook 19 on its other end engaging an eye on theunder side of the cross head. By applying pressure to the pedal themechanism operates in the same manner as when the hand is used.

To prevent flies and other insects from collecting around the mouth ofthe churn, a rod 20 is fitted in an opening in the cross head 8 andextends downwardly at an angle thereto beyond the churn and carries onits lower end a fan 21 of any approved. form directed toward the churnat the most effective angle. A thumb screw 22 holds the rod 20 in thecross head. The operation of the mechanism raises and lowers the fan,creating a current of air of suflicient force to drive insects,especially flies, away from the churn.

The numerals 23 and 24 indicate two vertically disposed rods fittingadjustably in apertures in the cross head 8 and held fixed therein bythumb screws 25. These rods extend sufficiently high to be above thehead of a person operating the churn when the mechanism is in its lowestposition. The upper ends of the rods 23 and 2% are preferably enlargedfor the attachment to each of a fan 26 which may be an ordinary palmleaf fan or a fan constructed especially for the purpose. The fansproject from the rods over the head of the person at the churn and whenthe mechanism is operated they produce a cooling effect as they rise andfall. Additional fans may be placed in the upper ends of the rods 23 and24 in holes 27 at right angles to the holes supporting the fans 26. Inthe side of the cross head a hole 28 made for a fan, its handle beingsecured by a thumb screw 29. As thus constructed and arranged the fansmay be changed or adjusted to any position desired and placed at themost effective angles for cooling the operator.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. A churn operating mechanism comprising a base board for supporting achurn, spaced vertical guide bars or rods rising from said base board, acoiled spring loosely surrounding each guide bar or rod and resting onthe platform, a cross head supported on the upper ends of said springsand having end perforations for sliding on said guide bars or rods, aninclined socketin said cross head for a slidable rod having anadjustable fan on its lower end and a thumb screw for fastening saidinclined rod to the cross head the latter having an aperture for theadjustable churn dasher rod and means for fastening the cross head tosaid rod.

2. A churn operating mechanism comprising a base board for supporting achurn, spaced vertical guide bars or rods firmly seated in said base, acoiled spring loosely surrounding each of said guide bars or rods,

a cross head seated on the upper ends of said springs and having acentral opening in which a churn dasher rod may be adjustably mounted,and end perforations for said vertical guide bars or rods to freely passthrough, means for securing the dasher rod to the cross head, aremovable standard or guide frame on said base, a folding arm pivoted tosaid standard, a pedal hinged to the outer end of said arm and extendingthrough said standard or guide frame, and a connection between saidpedal and said cross head.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
